All malignant neoplasms of the thyroid gland registered during the study period were studied, and their demographic and medical data was evaluated and, compared to identify the epidemiology and prognosis factors related to survival. SPSS 16 was used for statistical analysis. Results: Of the total, there were 100 (28%) male and 256 (72%) female subjects, with their mean age being 12.6 +/- 8.4 years. In terms of the disease, there was no statistically significant difference between the two genders (3=0.65). The five-year survival rate was 345 (97%) in patients aged 5-25 years.
